Sample No.: DRPA78002

Location: Derrick Peak

Field No.: 303

Weight (gms): 7188.0

Meteorite Type: Iron

Physical Description:

The B surface of this 24 x 22 x 9.5 cm specimen was in contact with the ice at the time of recovery. The B surface is irregular; an area ~5 cm long and 1.5 cm wide is ropy in appearance and has higher relief than the surrounding metal, which is probably due to preferential weathering of this material (schreibersite?). The T surface has many regmaglypts, some of the deeper of which are stained by hydrous iron oxides. The S surface is partially covered with a yellowish-brown evaporate deposit. The S side of the sample is thicker than the N edge, thus resulting in an overall wedge shape for the specimen.
